Title: Wet jigging machine for coal processing etc.
Inventor: HUBNER FRIEDHELM
IPC: F16K31/06
Filed: 1985-04-25
Abstract: Wet jigging machines for treating minerals, esp. coal, employ rotary butterfly valves actuated by rotary magnets. In an initial starting up period of valve rotation, lasting e.g. 70-200 (140) milliseconds, the valve drive is supplied with high potential (50-150 volts), while during the remainder of a cycle a lesser potential (10-30 volts) is supplied. Valve rotation may be through 20-70 (50) deg. and limited by a mechanical and/or electrical stop. The two different voltages, normally DC, may be derived from separate tappings of a single transformer. Power from main supply is electrically controlled to provide the different potentials.
